...I think if you have everything set up (formatted EFI partition with bootable flag, other data partitions allocated) you should go ahead and try and install something. You can skip formatting during the install, the installer should detect the EFI partition; they have to do this for dual boot windows installs. It does sound like grub should use the EFI partition.

| Mar 15, 2015 at 12:51 | comment | added | goldilocks | Okay. I don't think you have to do anything more than ensure the partition is the right type -- and evidently FAT formatted (it could work without an fs, BTW, which is why I assumed that). Have a look here: superuser.com/questions/764799/… <- Although this person used windows in the end, if you look at the answers they are saying the purpose of the EFI partition is to hold bootloaders installed by OS's, and at least some current linux install disks will do exactly that. Since it's fat formatted, you should be able to look at it before and after... | |
| Mar 15, 2015 at 12:42 | comment | added | JDługosz | I know how MBR Extended partitions work. The EFI has a predefined UUID, and doesn't care about labels. It's formatted as FAT32, not unformatted (how could it work?). Point is, no options on 'new' or anywhere else allowed entering the distinguished UUID, or reports the UUID of existing partitions. | |
| Mar 15, 2015 at 12:32 | comment | added | goldilocks | Re the gparted screenshot: Primary vs. logical/extended partitions are characteristics of MBR based drives. Because the MBR table is only big enough to reference 4 primary partitions, if you want more you must make one a "logical partition" which is really just another table holding references to "extended partitions" (which are normal, but possibly not bootable). GPT drives don't have this limitation. So if you only have the choice to create primary partitions, it's likely a GPT context. The EFI partition is a normal one, just it's small, has a special label, and no filesystem. | |

I saw the italics -- but it does not make a lot of sense unless you explain why you have been unable to do this -- the easiest way to do that is to explain what you actually tried and what actually happened. Otherwise people have to guess where you're at and are disinclined to go through "Oh no I did that already", etc. Anyway, if you want to create a GPT disk, start with fdisk and use the g option. Then you create the partitions, including the EFI one. I'd leave gparted out of this if you can't get it to work.
